Las especies reactivas del oxígeno (ROS), superóxido (O2o-), peróxido de hidrógeno (H2O2), y radical hidroxilo (OHo), se generan a partir de la reducción parcial del oxígeno molecular durante procesos ...
Gabrielli, Natalia (Date of defense: 2012-12-04)
Hydrogen peroxide (H2O2), a reactive oxygen species (ROS), is involved in both oxidative stress and signaling cascades in a dosage dependent manner. Its toxicity is partially explained through reactivity ...

Proteostasis is the proper homeostasis of the concentration and the molecular structure of the proteins, which preserves the integrity of the proteome. Proteo-stasis is constantly challenged by intrinsic ...
Zuin, Alice (Date of defense: 2009-10-15)
En Schizosaccharomyces pombe, la ruta de la MAP quinasa Sty1 se activa por peróxido de hidrógeno extracelular para inducir una respuesta celular antioxidante. Sin embargo, también puede activarse por ...
